SELF-ADJUSTING SPRING-HINGE.

Specification of Letters Patent.

Application filed December 9, 1909. Serial No. 532,165.

Spring-Hinges, of which the following is a and frame.

specification.

This invention relates to self-adjusting spring hinges, especiallyadapted to be used in connection with cold storage doors the objectbeing to provide a hinge which is so constructed that compression willbe obtained on the gasket of the door so as to form an exceedingly tightjoint.

Another object of my invention is to provide a hinge which isexceedingly simple and cheap in construction and one which is verystrong and durable, the parts being so mounted that the door will besupported in such a manner that all danger of the same become jammed isprevented.

A further object of my invention is to provide a hinge which is soconstructed that a door carried thereby will be held within the doorframe under tension at all times in such a manner that the gasket aroundthe door will be compressed by the pressure of the spring so as toinsure an air tight joint.

With these objects in view, my invention consists in the novel featuresof construction, hereinafter fully described, pointed out in the claimand shown in the accompanying drawings, in which:

Figure 1 is a front elevation of my improved self-adjusting spring hingeshowing the same in position on a cold storage door Fig. 2 is ahorizontal section through the door and frame taken above the hinge, thecylinder of the hinge being broken away. Fig. 3 is a vertical sectiontaken on the line 33 of Fig. 2.

Referring to the drawing A indicates the door frame of a cold storagebuilding or room, B the door for closing the same and C my improvedhinge for supporting the door within the frame so that the same will beheld therein under the tension of the spring at all times as will behereinafter fully described. 7

In carrying out my improved invention, I employ a cylindrical casing Dadapted to be embedded in the wall of the building or room under thefacing of the door frame in alinement with an opening formed in the doorframe through which extends the collar E of a facing plate F which issecured in position on the door frame by lag bolts G so as to hold thesame firmly thereon and said collar is provided with an annularlyreduced portion E adapted'to fit within the open end of the cylinder Dso as to form a snug joint and for securing the collar within thecylinder, I provide the cylinder D with a threaded bore D in which ismounted a set screw D adapted to engage the collar as clearly shown.

Extending through the face plate F and collar E is a stem H of aU-shaped head I, the arms of which are apertured as clearly shownthrough which is adapted to extend a pintle bolt J on which is pivotallymounted the eye K of a strap L which is provided with a series .ofopenings through which lag bolts L c re adapted to pass for securing thesame to the outer face of the door and this strap be formed of anydesign desired. Arranged on the pintle bolt J under the eye K is awasher M forming a bearing for the eye so as to allow the eye to turnfreely on the bolt in order to allow the door to swing easily.

The inner end of the stem H is provided with a threaded bore H overwhich is ar ranged a washer N which is secured in po sition by a setscrew N and surrounding the stem H between the washer N and the end ofthe collar E is a coil spring 0 the tendency of which is to draw thestem inwardly so that the head will be drawn tightly against the faceplate at all times and it will be seen that by this construction thegasket on the door will be compressed when the door is closed so as toform an air tight joint. 7

From the foregoing description, it will be seen that I have provided aself-adjusting spring hinge which is so constructed that the same can bereadily attached to a cold storage door and frame so as to hold the doortightly closed within the frame under the tension of the springs of thehinge whereby the packing material carried by the frame and door will becompressed when the door is closed.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is:

In a device of the kind described, the combination with a cylindricalcasing, of a plate having a collar the inner end of which is reduced andfitted into the end of the casing,

a stem extending through the plate and colstrep adapted to be secured toa door said lar, and bifurcated at its outer end, lts instrap beingpivotally connected to the bifurner end having a threaded bore, a Washercated outer end of stem as set forth.

arranged upon the end of stem, a screw for RICHARD E. JONES. holding thesame in place, a spring sur- Witnesses:

rounding said stem and bearing upon said C. L. KEEDY,

washer and reduced end of collar, and a R. M. KEEDY.
